Device and Method for Calibrating Coordinate System of 3d Camera and Robotic Arm

2. The method of claim 1, wherein the point cloud data is converted using a 3D information depth map with internal parameters of the 3D camera.

3. The method of claim 1, wherein the Z value difference is a difference between z-axis coordinates of the set of adjacent point clouds in a coordinate system of the 3D camera.

4. The method of claim 3, wherein the vector angle is an angle between a position vector formed by the set of adjacent point clouds and a horizontal or a vertical axis in the coordinate system of the 3D camera.

5. The method of claim 4, wherein the resolution of the point cloud image is set by the 3D camera, the slope of a plane of each plate is constant, differences between the z-axis coordinates of different sets of adjacent point clouds on the plane in the camera coordinate system are the same, the Z value differences of different sets of adjacent point clouds on the plane are the same, and the vector angles of different sets of adjacent point clouds on the plane are the same.
